“…Assuming that autochthonic CCHFV strain has established foci where it circulates within North Macedonia, the main trigger responsible for changes in CCHFV transmission dynamic and stochasticity could be climate changes potentially affecting tick ecology and the extrinsic incubation of the virus in its vectors. As average temperature recorded in North Macedonia is constantly increasing [34], repercussion on tick search activity and host parasitic load is expected [35,36]. This environment promotes CCHFV circulation, increasing the chance for susceptible individual to be exposed to bite of infected tick.…”

“…This was mainly due to security issues resulting in the temporary prohibition of hunting and agricultural activities, followed by the reopening of these areas after several years with the sudden exposure of humans to highly infectious ticks ( 105 ). This was also concomitant to higher spring temperatures over several successive years within the country that accelerated the development cycle of the tick vector H. marginatum , decreased its density-independent mortality, and thus increased populations available to become infected ( 106 ). Kulichenko in the Russian Federation ( 106 ) and Vescio in Bulgaria ( 107 ) also mentioned climate as a main factor impacting the development of CCHFV tick vectors and thus local virus circulation.…”
